FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC353/74ACT353 contains two identical
4-input multiplexers with 3-state outputs. They select two bits
from four sources selected by common Select inputs (S0, S1).
The 4-input multiplexers have individual Output Enable (OEa,
OEb) inputs which, when HIGH, force the outputs to a high
impedance (High Z) state. The logic equations for the outputs
are shown below:
Za = OEa
(I0a
S1
S0+I1a
S1
S0+
I2a
S1
S0+I3a
S1
S0)
Zb = OEb
(I0b
S1
S0+I1b
S1
S0+
I2b
S1
S0+I3b
S1
S0)
If the outputs of 3-state devices are tied together, all but one
device must be in the high impedance state to avoid high
currents that would exceed the maximum ratings. Designers
should ensure that Output Enable signals to 3-state devices
whose outputs are tied together are designed so that there is
no overlap.
